GRN® 135x160x15 NBR TC - Double Lip Radial Shaft Oil Seal

Product Description

GRN® 135x160x15 NBR TC is a double lip radial shaft oil seal (Simmerring) manufactured from nitrile butadiene rubber (NBR). Its nominal dimensions are 135x160x15 mm, with an inner diameter of 135 mm, an outer diameter of 160 mm and an axial width of 15 mm. The TC sealing profile features a primary sealing lip and an additional dust exclusion lip, designed to reduce lubricant leakage and limit contamination ingress into the sealing area.

The GRN® 135x160x15 oil seal is designed for installation on a shaft with a nominal diameter of 135 mm and in a housing bore with a nominal diameter of 160 mm.

Its primary function is to help retain oil or grease inside rotating mechanical equipment. The additional dust exclusion lip helps protect the main sealing interface against dust, dirt and fine particles.

The nominal radial cross-section height is 12.5 mm.

Due to the large shaft diameter and relatively small difference between the inner and outer diameters, correct seal selection, shaft surface condition, component alignment and operating conditions are particularly important.

Technical note: The product identification, dimensions, material and sealing profile are based on the supplied designation. Without verified manufacturer documentation for this specific GRN® product, no particular NBR hardness, operating temperature range, permissible pressure, maximum shaft surface speed or exact spring construction should be assumed.

GRN® 135x160x15 Oil Seal Dimensions

The designation 135x160x15 mm defines three essential installation dimensions:

• Shaft diameter: 135 mm.

• Housing bore diameter: 160 mm.

• Oil seal width: 15 mm.

The nominal radial cross-section height is 12.5 mm.

This value is a geometric calculation based on the difference between the outer and inner diameters. It does not represent the thickness of the elastomer layer or the width of the sealing lip.

All dimensions are nominal. Installation tolerances must be selected according to the equipment's technical documentation and the requirements of the sealing design.

What Does GRN® 135x160x15 NBR TC Mean?

GRN® - Product Brand

Products under this brand are offered by simmering.pl, a supplier of technical components for industrial and maintenance applications.

135x160x15 - Nominal Dimensions

The first number indicates the shaft diameter, the second number identifies the housing bore diameter, and the third number specifies the axial width.

For this product:

• d = 135 mm.

• D = 160 mm.

• b = 15 mm.

NBR - Nitrile Butadiene Rubber

NBR is a synthetic elastomer widely used in sealing applications involving many mineral oils and lubricating greases.

TC - Double Lip Sealing Profile

The TC profile identifies a construction featuring:

• A primary sealing lip responsible for retaining the lubricant.

• An additional dust exclusion lip designed to limit contamination ingress.

However, the sealing profile designation alone does not guarantee complete interchangeability between all oil seal designs from different manufacturers.

Construction and Operating Principle of the Double Lip Oil Seal

Primary Sealing Lip

The primary sealing lip creates dynamic contact with the rotating shaft surface.

During operation, its purpose is to reduce the movement of lubricant from inside the mechanical assembly to the surrounding environment.

Sealing performance depends on several factors, particularly:

• Sealing lip geometry.

• Shaft surface quality.

• Correct lubrication.

• Shaft surface speed.

• Operating temperature.

• Shaft and housing alignment.

• Actual pressure conditions inside the housing.

Additional Dust Exclusion Lip

The secondary lip creates an additional barrier against external contaminants.

Its purpose is to limit the entry of dust, dirt and fine particles into the main sealing area.

This can be particularly important in equipment operating in environments where contamination may accelerate wear of the contacting surfaces.

However, the dust exclusion lip does not guarantee complete sealing against pressurized water or provide protection under every environmental condition.

Garter Spring

Typical TC radial shaft oil seals use a garter spring to help maintain contact between the primary sealing lip and the rotating shaft.

The exact spring construction in the GRN® 135x160x15 NBR TC oil seal requires confirmation from the manufacturer's documentation.

Oil Seal Body

Typical TC oil seals feature internal metal reinforcement and a rubber-covered outer diameter.

The body helps maintain the geometry of the seal and ensures correct positioning within the housing bore.

The detailed body construction of this specific product has not been independently verified.

NBR Material - Properties and Chemical Resistance

Nitrile Butadiene Rubber is one of the most widely used elastomer materials in radial shaft oil seals.

Its important properties include:

• Good resistance to many mineral oils.

• Compatibility with numerous mineral oil-based lubricating greases.

• Elasticity required for dynamic shaft sealing.

• Suitability for appropriately designed rotating mechanical assemblies.

However, NBR is not a universal sealing material.

Chemical resistance depends on the elastomer compound, operating temperature and duration of exposure.

Compatibility with all synthetic oils, fuels, solvents or aggressive chemicals should not be assumed.

The permissible operating temperature range for this specific product also requires confirmation from the manufacturer.

TC Double Lip vs Single Lip Radial Shaft Oil Seals

The additional dust exclusion lip can be beneficial in environments exposed to contamination.

However, this does not mean that a double lip construction is always preferable to a single lip design.

Selection depends on the specific equipment, lubrication conditions, available installation space and friction requirements.

GRN® 135x160x15 Compared with Other Oil Seal Dimensions

When searching for a replacement oil seal, all three dimensions must be considered.

These dimensions are presented for geometric comparison only.

135x160x15 vs 135x165x12

Both oil seals have an inner diameter of 135 mm, but their outer diameters and axial widths are different.

The 135x165x12 variant requires a housing bore with a nominal diameter of 165 mm and has an axial width of 12 mm.

It is not a direct dimensional replacement for the 135x160x15 oil seal.

135x160x15 vs 135x170x15

Both variants have the same inner diameter and axial width.

However, their outer diameters differ, measuring 160 mm and 170 mm respectively.

The 135x170x15 variant requires a larger housing bore.

Matching shaft diameter alone is not sufficient to confirm oil seal interchangeability.

Shaft Surface Speed for a 135 mm Shaft

Shaft surface speed can be calculated using the following formula:

Where:

• v - shaft surface speed in m/s.

• d - shaft diameter in mm.

• n - rotational speed in rpm.

For a shaft diameter of 135 mm:

The values above are based solely on geometric calculations.

They do not represent verified permissible operating speeds for the GRN® 135x160x15 NBR TC oil seal.

With a large shaft diameter, linear surface speed may be substantial even at moderate rotational speeds.

Therefore, lubrication conditions, operating temperature and manufacturer-approved performance limits must be considered.

Typical Applications of TC Double Lip Radial Shaft Oil Seals

This type of oil seal is used in appropriately designed rotating mechanical assemblies where lubricant retention and contamination protection are required.

General application categories for double lip radial shaft oil seals include:

• Mechanical drive systems.

• Gearboxes and rotating assemblies.

• Bearing housings.

• Industrial machinery.

• Equipment with rotating shafts.

These are typical application areas for this category of sealing components, not verified OEM applications of the specific GRN® 135x160x15 product.

Final suitability depends on equipment design and operating conditions.

Installation of the 135x160x15 Oil Seal

Correct installation has a significant influence on sealing performance and service life.

Before installation, clean the shaft and housing bore and check for scratches, corrosion, burrs or wear grooves.

The oil seal should be installed evenly using a tool suitable for its dimensions.

Installation force must not be transmitted through the sealing lips.

In typical applications, the primary sealing lip should face the retained lubricant, while the additional dust exclusion lip should face the external environment.

Final installation orientation must follow the equipment manufacturer's documentation.

Before operation, ensure proper lubrication of the primary sealing lip contact area. In double lip constructions, lubrication requirements for the space between the lips must also be considered.
